One Delta-Link MADI HD delivers 256 channels of digital audio from a single hardware interface. MADI HD uses a single-cable interconnect system between Pro Tools DSP cards and MADI cards. Fiber-optic MADI allows distances up to 3,280 feet between the Pro Tools system and other MADI equipment. Remote audio routing to and from Pro Tools is also possible with MADI routing equipment.

The Delta-Link MADI HD features two primary port interfaces (32 channels each) to a Pro Tools HD card and two optical MADI ports. Each MADI port offers 56 or 64 MADI digital inputs and outputs at up to 48 kHz; 28 or 32 MADI digital inputs and outputs at up to 96 kHz; and 14 or 16 MADI digital inputs and outputs at up to 192 kHz. The unit also includes word clock/super clock input. All input and output channels can be used simultaneously in any configuration. A USB interface is provided for user control and/or future firmware updates.

SSL Xlogic Alpha-Link MADI-SX

The initial Alpha-Link product release comprises three models with 24-channel SSL-enhanced AD/DA converter circuitry that offer a choice of digital audio formats. The Alpha-Link MADI-SX ($3,595) is a MADI- and AES/EBU-based converter, while the Alpha-Link MADI-AX ($3,595) and Alpha-Link AX ($2,695) are ADAT Lightpipe-based converters.

Each unit offers a comprehensive I/O routing matrix for setting up global connections between the various I/O connections. The front panel also includes a headphone jack and a metering section for the analog inputs and outputs with an AD/DA selection button, mode indicator LEDs and 24 tri-color level LEDs.

All Alpha-Link units can be used as stand-alone format converters or with a Soundscape Mixpander PCI card as an I/O solution for native PC-based audio workstations. When the unit is connected to a Mixpander, the inputs and outputs can be routed individually from the PC using the Soundscape Mixer software.
